Description

  The present invention relates to an acupuncture needle used for acupuncture, and more particularly, to an acupuncture needle with a drug that has both the efficacy of a drug in addition to the efficacy of acupuncture.

Conventionally, as an acupuncture needle used for acupuncture, in addition to the efficacy effect of a normal acupuncture, there is one that can administer a drug percutaneously into the body.
Specifically, a narrow groove substantially parallel to the axis line is provided on the surface of the needle body as in Patent Document 1, and a medicine is held in the narrow groove, or a needle body as in Patent Document 2 Are provided with pores penetrating in the direction intersecting the axis, and a drug is held in the pores.

By inserting such an acupuncture needle with a drug into a treatment site (acupuncture), the effect of normal acupuncture can be obtained, and the drug is transdermally administered into the body.

However, in the above-mentioned acupuncture needle with a medicine, it is necessary to process a groove or a hole in a thin needle in the first place, and it is difficult to manufacture at a low cost and it is also difficult to ensure the strength of the needle. Moreover, since the groove | channel and hole for a chemical | medical agent holding must be very small, a sufficient quantity of chemical | medical agents cannot be hold | maintained, the chemical | medical agent to be administered also becomes a small quantity, and a pharmaceutical effect is restrict | limited.
In view of such conventional problems, the present invention can be easily manufactured without processing the needle body, and in addition to the efficacy effect of normal acupuncture treatment, a desired amount of drug can be administered transcutaneously ( It is an object to provide an acupuncture needle with a drug capable of being absorbed.

  For this reason, in the present invention, a bandage formed with an adhesive layer on one side and a needle body fixed to the center of the bandage and having a needle tip protruding from the adhesive layer of the bandage are configured. It is set as the structure which mixes a chemical | medical agent with the said adhesive using an acupuncture needle.

  According to the present invention, when the needle is inserted into the skin, the drug is mixed with the adhesive of the adhesive bandage to be attached to the skin in order to place the needle. An absorption effect can be produced.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows an embodiment of acupuncture needle with a medicine according to the present invention, wherein (a) is a plan view, (b) is a front view, and (c) is a bottom view. FIG. 2 is an enlarged cross-sectional view of a portion A in FIG.
This acupuncture needle (circular needle) is composed of a bandage (adhesive tape) 1, a release paper 2, a needle body 3, and a resin material 4.

The adhesive bandage (adhesive tape) 1 is circular, has adhesiveness on one side, and is provided with a hole 1a in the center.
The release paper 2 has a circular shape, and its diameter is slightly larger than the diameter of the adhesive bandage 1. The release paper 2 has a hole 2 a at the center and is detachably attached to the adhesive surface side of the adhesive bandage 1. Further, the release paper 2 is divided by a dividing line 2b passing through the hole 2a to facilitate peeling or the like during the treatment.

The needle body 3 is made of metal (made of stainless steel) and is bent in an L shape. The distal end portion (needle tip) 3a of the needle body 3 protrudes through the holes 1a and 2a of the adhesive bandage 1 and the release paper 2, and is inserted subcutaneously through the protruding portion. On the other hand, the base end portion 3b is processed into a flat shape, and is disposed on the non-adhesive surface side of the adhesive bandage 1 substantially in parallel therewith.
The resin material 4 is injection-molded or potted (resin pile processing) on the non-adhesive surface of the adhesive bandage 1 so as to cover the proximal end portion 3 b of the needle body 3, thereby fixing the needle body 3.

  As described above, the acupuncture needle (circular needle) according to the present embodiment has a substantially circular adhesive bandage (adhesive tape) 1 having a single-sided adhesive surface and a hole in the center, and the adhesive surface side of the adhesive bandage 1 A release paper 2 having a hole at the center, a distal end projecting through the holes of the adhesive bandage 1 and the release paper 2, and a base end is disposed on the non-adhesive surface side of the adhesive bandage 1. Needle body 3 and resin material 4 which is molded on the non-adhesive surface of adhesive bandage 1 and covers and fixes the base end of needle body 3.

Here, as shown in FIG. 3, the adhesive bandage (adhesive tape) 1 is composed of a base material 11 made of paper, cloth, non-woven fabric, or plastic tape, and an adhesive provided on one side of the base material 11. The two-layer structure of the layer 12 is a two-layer structure of a base material 11 and a pressure-sensitive adhesive layer 12 in which a drug is mixed in a pressure-sensitive adhesive.
The drug may have a desired medicinal effect such as anti-inflammatory analgesics, vitamins, antiallergic agents, etc., from those that give a cool feeling such as l-menthol and d-camphor, or a combination thereof. .

FIG. 4 shows a state (packaging form) in which the main needle is stored in the storage container.
The storage container is made of a resin container body 5 having a recess that can store a bag (circle skin needle) with the needle tip down, and a container body 5 with the bag (circle skin needle) stored in the container body 5. And a sterilizing gas permeable sheet material 6 that is detachably attached to the outer frame portion of the upper surface of 5 and seals the opening of the recess. Then, after storage and sealing, sterilization treatment (gas sterilization) is performed to complete.

When the acupuncture needle (circular needle) completed as described above is used, after removing the acupuncture needle (circular needle) from the storage container, a part of the release paper 2 is peeled off from the adhesive bandage 1 and the needle body 3 is removed. Put the exposed part of the adhesive surface on the skin and fix it while putting it in the pot and piercing it. Further, the remaining part of the release paper 2 is peeled off, and the adhesive surface of this part is also attached to the skin.
According to the present embodiment, the drug is mixed with the adhesive layer 12 of the adhesive bandage 1 for indwelling the acupuncture needle on the skin, thereby providing a percutaneous absorption effect of the drug in addition to a normal acupuncture effect. be able to.

Moreover, it is easy to mix a chemical | medical agent with an adhesive, mass production is possible, and an acupuncture needle with a chemical | medical agent can be provided cheaply.
Even if it sees about a usage method, it peels off the release paper 2 from the adhesive bandage 1, and only sticks it in a predetermined position, and it is very simple.
Furthermore, it has the following effects as compared with a normal patch (tape preparation). The stratum corneum of the skin has a high barrier property, and the penetration of the drug from the tape preparation must be slow. On the other hand, since the needle is inserted from the stratum corneum to the dermis layer by applying it to the acupuncture needle as in the present invention, the penetration rate of the drug is increased. In addition, as an effect of acupuncture, the increase in blood flow in the tissue can accelerate the onset of medicinal effects.

In particular, the illustrated circular needle shape allows the adhesive bandage around the needle tip to be in close contact with the skin and allows the drug to penetrate effectively.
Although the embodiments of the present invention have been described, it is not intended to limit the present invention, and various modifications may be made within the spirit and scope of the claims when the present invention is implemented. Can do.

For example, the number of needles is not limited to one, and the degree of medicinal effect and speed can be controlled by increasing the number of needles.
In addition, selection of a drug can create an acupuncture + cooling action and an acupuncture + heat action, further enhancing the acupuncture treatment effect.
